In the lab, chemist analyzed a sample of methanol and found that it was made of 6.20 g of carbon, 4.10 g of hydrogen, and 15.90 g of oxygen. What is the percent composition of each element? Round each answer to the tenths place.

for points guys

i just learnt this recently but i need to look through my notes again

jjj89t'ji; it hink the answer is your mom is not si

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
